IMPROVEMENT IN HOlSTlNG-BUCKETS.

Specification forming part of Letters Patent No. 212,317, dated February18, 1879; application filed January 9, 1879. 7

To all whom it may concern:

Be it known that I, FREDERICK H. C. MEY, of Buffalo, in the county ofErie and State of New York, have invented certain new and usefulImprovements on an Elevator-Bucket; and I do hereby declare that thefollowing description of my said invention, taken in connection with theaccompanying sheet of drawings, forms a full, clear, and exactspecification, which will enable others skilled in the art to which itappertains to make and use the same.

This invention has special reference to improvements onelevator-buckets; and it consists in the peculiar arrangement of partsand details of construction, as hereinafter first fully set forth anddescribed, and then pointed out in the claims.

In the drawings already mentioned, Figure I is a perspective view of myimproved bucket. Fig. 2 is a front, and Fig. 3 an end, elevation. Fig. 4is a plan.

Like parts are designated by corresponding letters of reference in allthe figures.

A is the band, and B B are the two heads, of my bucket. O is the belly.This band, which I prefer to cast of malleable iron or steel, I provideat opposite sides with projecting lugs D D, the inner opposite sides ofwhich are beveledto form a dovetail mortise or socket, into which Iplace a cross-bar, E, having on both its ends lateral flanges F, theedges of which are also beveledto fit the dovetail socket or mortise,said cross-bar being retained in position by rivets, screws, or similarmeans, f.

The front side, G, of this band is made narrowerthan therear side, G,while the sides G, Figs. 1, 3, and 4, are tapered accordingly. Thisarrangement affords a perfect distribution of the material employed, andproduces a band of superior strength to one having an equal amount ofmetal in the band, but the band made of equal width and thicknessthroughout, inasmuch as the rear side, G, in my bucket, which isattached to the usual belting and sustains the weight of the bucket andits load, has the preponderance of metal, while the front edge, which isnot subjected to any particular strain, has the smaller portion thereof.

The sides B have preferably set-up edges bthat is to say, have theiredges bent at right angles to their planes and they are riveted to thebelly O, and, together with the latter,

produce a bucket which is narrower at its bottom than at its top. Thisarrangement has the particular advantage of causing an easy discharge ofthe bucket, particularly with such substances as flour, cement, sand, orother wet or slightly-adhesive substances, which are very apt to stickto the bucket if the discharge is not instantaneous.

In elevator-buckets, the side which is fastened to the belting is alwaysvery apt to be bulged in, on account of its strikingthe driving-pulleys,&c. To avoid this obstacle I provide the heads B B with stiffeners B,consisting of sheet-metal strips riveted or otherwise secured to saidbucket.

The particular advantages of a bucket constructed as described are that,by means of the arrangement with the band of the cross-bar E, insertedinto the dovetail sockets described, I am enabled to insert or withdrawsaid crossbars at any time without removing them from the belting. Thus,for instance, in elevating light substances the cross-bars mayberemoved,and the buckets used without them, while, when afterward comparativelyheavy substances are to be elevated, they may be readily reinserted. Itgives me, furthermore, the advantage of supplying the purchaser withbuckets without bars, and at any time thereafter when desired with thecrossbars.

It will be readily observed that, on account of the beveled socket andtenon arrangement of the band and cross-bar, the upper opposite sides ofsaid band are drawn tightly together, and the front side of the sameperfectly braced, much more so than in bands having a rigid cross-barformed in one piece with said band, while the advantages derived fromsuch con struction render the bucket more desirable and cheaper, owingto its greater freedom from loss in casting.

Having thus fully described my invention, I claim as new and desire tosecure to me by Letters Patent 1. An elevator-bucket having theside-stifieners B, as and for the purpose stated.

2. As an improved article of manufacture, an elevator-bucket having theflat ends arranged convergingly, as specified, and the hand providedwith projections D D, forming a dovetail socket for the cross-bar E, asand for the purpose stated.

3. In elevator-buckets, a band having its rear side, G, made wider andthicker than its front side, G, and the sides G made tapering, as andfor the object specified.

4. 1n elevator-buckets, a band having dovetail sockets, as specified,for the purpose stated.

5. The combination, with the band A, having the projections D D, formingsockets, of the cross-bar E, having lateral flanges F, formin g tenons,said cross-bar being arranged to be inserted into said socket andretained therein 2y the fastening f, as and for the object speci- Intestimony that I claim the foregoing as my invention I have hereto setmy hand and aiiixed my seal in the presence of two subscribingwitnesses.
